Outdoor Knight Boiler User’s Information Manual
Please read before proceeding
The Outdoor Knight Boiler Installation
and Operation Manual along with the
Outdoor Knight Boiler Service Manual
are for use only by a qualified heating
installer/service technician. Refer only
to this User’s Information Manual for
your reference. Improper installation,
adjustment, alteration, service or
maintenance can cause property damage,
personal injury (exposure to hazardous
materials) or loss of life. Installation
and service must be performed by a
qualified installer, service agency or the
gas supplier (who must read and follow
the supplied instruction before installing,
servicing, or removing this boiler. This
boiler contains materials that have been
identified as carcinogenic, or possibly
carcinogenic, to humans).
Failure to adhere to the guidelines on this
page can result in severe personal injury,
death, or substantial property damage.
Boiler service and maintenance –
• To avoid electric shock, disconnect electrical supply
before performing maintenance.
• To avoid severe burns, allow boiler to cool before
performing maintenance.
Boiler operation –
• Do not install the appliance where it will be exposed to
freezing temperatures.
• Do not block flow of combustion or ventilation air to
the boiler. This boiler is equipped with a control which
will automatically shut down the boiler should air or
vent be blocked. If vent or air blockage is easily
accessible and removable, remove it. The boiler should
attempt to restart. If blockage is not obvious or cannot
be removed, have the boiler and system checked by a
qualified service technician.
• Should overheating occur or gas supply fail to shut off,
do not turn off or disconnect electrical supply to the
circulator. Instead, shut off the gas supply at a location
external to the appliance.
• Do not use this boiler if any part has been under water.
The possible damage to a flooded appliance can be
extensive and present numerous safety hazards. Any
appliance that has been under water must be replaced.
Boiler water –
• Thoroughly flush the system (without boiler
connected) to remove sediment. The high-efficiency
heat exchanger can be damaged by build-up or
corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing
compounds in the boiler system. Gaskets and seals in
the system may be damaged. This can result in
substantial property damage.
• Do not use “homemade cures” or “boiler patent
medicines”. Serious damage to the boiler, personnel,
and/or property may result.
• Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat
transfer, overheats the stainless steel heat exchanger,
and causes failure. Addition of oxygen carried in by
makeup water can cause internal corrosion. Leaks in
boiler or piping must be repaired at once to prevent
makeup water.
Freeze protection fluids –
• NEVER use automotive antifreeze. Use only inhibited
propylene glycol solutions, which are specifically
formulated for hydronic systems. Ethylene glycol is
toxic and can attack gaskets and seals used in hydronic
systems.
When calling or writing about the boiler
– Please have the boiler model and serial
number from the boiler rating plate.
Consider piping and installation when
determining boiler location.
Any claims for damage or shortage in
shipment must be filed immediately
against the transportation company by
the consignee.
Factory warranty (shipped with unit) does
not apply to units improperly installed or
improperly operated.

sure the system is pressurized. Lift the relief valve
top lever slightly, allowing water to relieve through
the valve and discharge piping.
3. If water flows freely, release the lever and allow the valve
to seat. Watch the end of the relief valve discharge pipe
to ensure that the valve does not weep after the line has
had time to drain. If the valve weeps, lift the seat again to
attempt to clean the valve seat. If the valve continues to
weep afterwards, contact your qualified service
technician to inspect the valve and system.
4. If water does not flow from the valve when you lift the
lever completely, the valve or discharge line may be
blocked. Immediately shut down the boiler, following
the operating instructions on page 9 of this manual. Call
your qualified service technician to inspect the boiler and
system.
Shut boiler down (unless boiler is used

In compliance with Energy Conservation Standards, this boiler
is equipped with outdoor air reset, a feature that saves energy
by reducing the boiler water temperature as the heating load
decreases. Three (3) individual outdoor resets for low outdoor
temperatures are available. The reset curve parameters can be
changed by the installer by accessing the Outdoor Reset menu.
There are three (3) individual user set points for better zone
control. These are listed as SH1 Set Point through SH3 Set
Point. These set points provide a maximum boiler water
temperature limit to the outdoor reset curve of each zone. The
boiler operating set point is calculated from the individual reset
curve of each zone. If multiple space heating set points are
calling for heat the highest set point has priority. The range is
SH Minimum Set point to SH Maximum Set point (32°F (0°C) -
190°F (88°C)). The default is 125°F (52°C).
By installing a tank sensor, the SMART SYSTEM control can
perform the tank thermostat function. The SMART SYSTEM
control automatically detects the presence of this sensor, and
generates a DHW call for heat when the tank temperature
drops 6°F (-14°C) below the tank set point differential (Tank
Set point Differential parameter), and finishes the call for heat
when the tank temperature reaches tank set point + offset.
This parameter can be changed by the installer by accessing the
DHW Tank Set point parameter. The temperature range of this
parameter is 68°F (20°C) to 190°F (88°C). The default value is
125°F (52°C).
Press the NAVIGATION dial once. A menu will appear
showing the SH1, SH2, SH3, and DHW Set Points. Rotate
the NAVIGATION dial until the arrow (>) is pointing to the
setting you wish to change. Press the NAVIGATION dial again.
